Abstract
Provided is a takeover method for cache partition recovery, including: determining whether a cluster has a four-controller topology, and when having the four-controller topology, setting a four-controller topology flag for each cache partition of the cluster; in response to monitoring that the cluster is changed to a cluster having a dual-controller topology and including a first node and a second node, determining whether a third node and a fourth node that exit the cluster belong to a same sub-cluster, and when belonging to the same sub-cluster, further determining whether cache partitions of the sub-cluster are set with the four-controller topology flag; and when set with the four-controller topology flag, further determining whether the sub-cluster is in a single-partition mode or dual-partition mode, and respectively taking over, by the first node and the second node, the third node and the fourth node based on the single-partition mode or dual-partition mode.
